Comm Ave Bridge Replacement Project to Start July 26

The Massachusetts Department of Transportation (MassDOT) is reminding members of the public of its upcoming intensive construction operations to replace the westbound side of the Commonwealth Avenue Bridge over 15 and one-half days from Thursday, July 26, through Saturday, Aug. 11.

During these construction operations, MassDOT said there will be significant service impacts to all modes of transportation in the Boston University/Saint Paul Street neighborhood of Boston along Commonwealth Avenue, including MBTA, commuter rail and Amtrak customers, vehicles along Commonwealth Avenue and the Boston University Bridge, and traffic on The Pike.

This $110 million bridge replacement project, which would take an estimated four to five years using conventional techniques with significant lane-takings and service disruptions, is scheduled for completion in 2019 under the accelerated plans. The westbound side of the bridge will be constructed this summer using three cranes that weigh 600 tons each. Crews will utilize this equipment to put in place 45 steel beams and 215 pre-fabricated concrete deck panels along with 680 cubic yards of concrete and 520 tons of hot mix asphalt.

The full upcoming travel impacts will be as follows:

Pedestrians and Bicyclists

Pedestrians and bicyclists will have access across the Commonwealth Avenue Bridge on the eastbound side throughout construction.

Download the Blue Bikes app on the App Store or Google Play to find a station near you. For a limited time, Blue Bikes is dropping their Single Trip Pass to $1 from July 26 – Aug. 11, available in the Blue Bikes app.

MassDOT is also partnering with the City of Boston to provide an additional temporary Blue Bikes station at Silber Way on Commonwealth Ave during the construction period.
